NAIL-MAKING MACHI'NE.

SPECIFICATION forming part of Letters Patent N0. 772,916, dated October 25, 1904.

- Application filed May 18, 1903. Serial No. 157,569. (No model.)

a subject of the King of Great Britain, residing at St. Henry, county of Hochelaga, Province of Quebec, Canada, have invented certain new and useful Improvements in Nail- Making Machines; and I do hereby declare that the following is a full, clear, and exactdescription of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to nail-making machines, and especially to that class which make what is known as wire nails.

The object of the invention is to produce a machine for the purpose mentioned which is very simple in construction. and which embodies an improved arrangement and mode of operation of the dies which form the nails.

It should be stated that the machine belongs to that class which form the nails in a continuous strip or wire as it passes through the machine.

The invention consists in the construction and combination of parts to be more fully described hereinafter, and definitely set forth in the claims.

In the drawings, which fully illustrate my invention, Figure 1 is a longitudinal vertical section of the machine.

.vertical section taken substantially on the line '2 2 of Fig. 1.

Fig. 3 is a side elevation of a portion of the mechanism, this view being upon a reduced scale and taken looking in the same direction as Fig. 1. Fig. 4 is a view taken at the dies, certain of the parts being shown in elevation and others in vertical section, as will appear. This view is upon an enlarged scale. Fig. 5 is an elevation of certain of the diesupon an enlarged scale. It represents substantially aportion of the dies as shown in Fig. 2.

Throughout thedrawings and specification the same numerals of reference denote like parts.

Referring more particularly tothe parts, 1.

tight and loose pulleys 7 and 8, as shown,

Fig. 2 is a transverse this anvil-die is normally maintained in a fixed which there are disposed a pair of alining bearings 4, as shown, and these hearings support the main shaft 5 in the manner indicated, the same being provided at its outer extremity with a fly-wheel 6, adjacent to which are the which pulleys afford means for driving the shaft 5', as will be readily understood.

Upon the upper side of the aforesaid plate 3there is mounted a block 9, attached to the same by suitable bolts 10. This block has a substantially vertical face 11, which is preferably square in form, as shown in Fig. 2. In this face 11 there is provided a transverselydisposed guide-slot 12, preferably of dovetail 5 form, as shown. The upper edge 13 of this slot passes continuously from edge to edge of the face 11, as shown; but the lower edge 14 is interrupted at one side by an'abutment 15 in the manner shown most clearly in Fig. 2. Upon this verticalface 1 1, across the said guiderecess 12, there is provided avertical plate 16, which is attached by means of suitable screws 17 as shown, and in the recess or guide 12 behind this plate there is placed an anvil-die 18, which consists substantially of a block of general rectangular form, but which has a beveled edge received by the lower edge 14 of the guide 12. It should be understood that position by means of the screws or bolts 19 and 20, which are mounted, respectively, in the abutment 15 and the plate 16, as shown. The extremity of thebolt 19 abuts the outer face of the anvil-die 18, and the extremity of 5 the screw 20 is received in the longitudinallydisposed slot 21, which is formed in the lateral face of the anvil-die 18, as shown. I Opposite to the said anvil-die 18 there is mounted a clamping-die 22, which is adapted to slide in 9 the said guide 12, being provided with beveled edges 23 for this purpose, as will be readily understood. The inner extremity of this die 22 is cut away at its upperedge, as indicated at 24, so as to form a substantially hori- IOO cave recesses 27' and 28, and these recesses, it should be understood, are adapted to cooperate to hold or clamp between them a wire 29, which is adapted to be passed between the dies. In order to allow the wire 29 to pass in the manner suggested, the said block 9 is provided with a guide-opening 30, which is provided with a sleeve 31, through which the wire passes, as indicated in Fig. 1. The manner of controlling the feeding movement of this wire will be described more fully hereinafter.

Upon the upper face 26 of the anvil-die 18 there is mounted a pointing-die 32, which has a beveled upper edge 33, cooperating with the edge 13 of the guide 12, and it should be understood that this die 32 is adapted to slide longitudinally in the guide 12. \Vithout going into the details of the operation at this point it may be stated that when the wire 29 is clamped, in the manner already suggested, between the dies 18 and 22 the die 32 is advanced in such a manner as to shear or cut off a portion of the wire in such a manner as to form a point for the nail. For this reason the lower edge 34 of the die 32 is tapered, as shown most clearly in Fig. 4.

For the purpose of actuating the die 22 the aforesaid shaft 5 is provided with a cam 35, which cam actuates the bell-crank lever 36 through the medium of the frictional roller 37, the said bell-crank lever being mounted upon a suitable bracket 38, which bracket is attached to the under side of the plate 3 aforesaid by means of suitable bolts 39. To the upper extremity of the vertical arm 40 of the bell-crank lever 36 there is pivotally attached a knuckle 41, which knuckle lies adjacent to the bracket 42, which bracket is piv otally carried at 42 upon the outer extremity of the die 22, as shown. In the knuckle 41 and the bracket 42 there is mounted an adjusting-bolt 43, having oppositely-disposed extensions 44, which are oppositely threaded, as will be readily understood, so that the rotation of the bolt will bring together or separate the knuckle and the die. The lower arm 45 of the aforesaid bell-crank lever 36 carries an adjustable stop-bolt 46, the upper extremity 47 of which abuts against the lower side of the aforesaid plate 3 in order to limit the movement of the bell-crank lever in one direction, as will be readily understood, and a spring 48 is provided which constrains the said bell-crank lever in a way to maintain the said extremity 47 against the said plate 3, in this manner normally maintaining the roller 37 against the face of the cam 35 in the manner shown. It should be understood that this bolt 46 passes through the opening 48 in the arm 45 and is adjustable longitudinally therein by reason of nuts 49. In order to actuate the die 32, an arrangement very similar to, that described for actuating the die 22 is adopted. To this end a cam 50 is provided, which is carried by the aforesaid shaft 5 and the lateral face of which is provided with a cam-groove 51, in which groove runs a friction-roller 52, the same being mounted upon the extremity of the lower arm 53 of a bell-crank lever 54, which bell-crank lever is substantially similar to the aforesaid bellcrank lever 36. The arrangement for attaching the upper extremity of the bell-crank le ver 54 to the die 32 is similar to the arrangement for attaching the bell-crank lever 36 to the die 22. This connection comprises a. knuckle and a bracket 56, which are pivoted, respectively, to the lever and the die, as shown, there being mounted between them an adjusting-bolt 57, comprising oppositelydisposed extensions 58, which are oppositely threaded, as will be readily umlerstood. The bell-crank lever 54 is mounted upon a bracket 58, carried by the under side of the plate 3, which bracket is substantially similar to the bracket 38 aforesaid.

The dies which form the heads of the nails or which cooperate to form the heads of the nails will now be described, together with the mechanism for actuating them.

Upon the face 11 aforesaid there are provided a pair of oppositely-disposed bosses 59, which are preferably of crowned or convex form, as shown in Fig. 1. In these bosses are mounted, respectively, the studs 66, and upon these studs there are loosely mounted the oppositely-disposed levers 61, which are arranged substantially vertically, as shown most clearly in Figs. 1 and At their upper extremities the faces 62 of these levers which are adjacent to the face 11 aforesaid are provided with undercut recesses 63, which are adapted to receive the dies 64, which dies have beveled lower edges to corres mnd with the undercut notches 63 and are retained in place by means of clamps 66, as shown. Near their rear faces these dies have recesses 64 for a purpose which will appear hereinafter. It should be understood that these two dies 64 are placed opposite to each other in such a manner that their adjacent vertical faces 67 may cooperate to clamp between them the wire 29. The mechanism for actuating these levers 61 will now be described. It consists simply of a cam 68, which is rigidly carried by the aforesaid shaft 5 and upon the face of which run the friction-rollers 61), carried by the lower extremities of the levers 61, as shown. It should be understood that in the operation of the machine the dies 64 clamp the wire between their faces 67, and after the wire has been securely clamped in this manner they are moved toward the, dies 18 and 32 in such a manner as to form a he: 1 between the faces of the dies, the operation in this respect being substantially the same as that found in other machines. In order to enable the levers 61 to rock upon the pivotstuds 60, the openings 70 through the levers to receive the said studs are of increased diameter near the faces of the levers, as indicated.

As indicated most clearly in Figs. 1 and 2, the

said table 3 is provided with a large opening 71, through which the aforesaid levers 61 pass, and in this same opening there is mounted a substantially vertical rocking lever 72,

the same being pivoted at 7 3 upon a bracket 7 4:, which bracket is mounted upon the upper face of the aforesaid plate 3 and adjustable longitudinally with respect to the wire 29 by reason of an elongated slot 75, through which slot a bolt 76 passes, the said bolt being mounted in the plate 3, as indicated. Near its up,- per extremity this rocking lever is provided with an opening 7 7 through which the wire 29 passes freely, and at the sides the rocking lever 72 has attached thereto links 78, which connect the same with the aforesaid levers 61, respectively. The lower extremity of the lever 72 carries a friction-roller 79, which runs upon the face 80 of a cam 81, which cam is mounted upon the aforesaid main shaft 5. A spring 82, which is received by a hook 83, affords means for constraining the lever 72 into such a position as will retain the roller 79 in contact with the cam 81. stood that as the shaft 5 rotates. the cam 81 operates to rotate the rocking lever 72 upon its pivot 73 in such a manner as to rock the levers61 forwardly through the medium of the links 78. This forward movement, however,'of the levers 61 and the dies 64 takes place when the wire has been clamped between the dies 64, and the forward movement of the dies forms the heads of the nails, as

already stated.

Arrangement is made for advancing or feeding the wire 29 through the machine, it being advanced periodically an amount substantially equal to the length of one nail. To this end theaforesaid block 9 and the plate 3 are provided with an opening 8 1, which passes through the same, and in this opening there is mounted a feed-lever 85, which is pivotally mounted upon a pin 86, carried by the aforesaid block. Near the upper extremity of this lever there is provided a rest 87, across which the wire 29 passes, and above this rest there is arranged a feed-dog 88, which is pivoted at 89 and provided with a sharp edge 90,

which'is disposed in the direction in which the wire is to be advanced and which lies adjacent to the upper face of the aforesaid rest in such a manner that the wire may be clamped thereupon, so as to advance the same, as will be readily understood. This leveris actuated from time to time by means of the rear face 91 of the aforesaid cam 50, which face cooperates with a friction-roller 92, which is carried by the lower extremity of the feed-lever 85, as shown in Fig. l, the said roller being constrained against the cam by means of the aforesaid spring 82, which spring was described in connection with the It should be underrocking lever 72. It will be observed that the extremity of this spring opposite to the hook 83 is attached in an opening 93, provided in the feeding-lever 85, as shown. It should beunderstood that as the nails are formed in the wire the continuity of the wire is not broken and the operation of forming the nails consist-s virtuallyin changing the form of the wire, so that it constitutes a succession of nails, the points of the nails being formed just behind the heads 96 of the nails next in ad- 'vance, as indicated in Fig. 1. Arrangement is made for preventing a retrogressive movement of the wire. To this end a block 97 is mounted near that part of the machine where the wire leaves the same, and upon this block is supported a rest 98, over which the wire passes and above which there is located a detent finger or pawl 99, having a sharpened point, as shown, and constrained by means of a spring 100 against the rest, as shown. As indicated, the wire 29 passes between the detent-finger 99 and the rest 98 in such a manner that the point of the finger 99 may engage behind the heads 96 of the nails in order to prevent any possible retrogressive movement of the wire, as will be readily under,- stood. In the lower portion of the block 97 there is mounted a set-screw 101, the extremity of which abuts against the outer face of the aforesaid member 7 4, in this manner facilitating the longitudinal adjustment of the member 74, which adjustment is made possible by the presence of the elongated slot 75 and made necessary in order to bring the co operating dies into proper relation with each other in forming the heads of the nails. Before the wire passes into the machine it passes through a guide or eye 102, which is carried above a suitable post-103, and behind this 'in the proper direction by a comparatively loose cross-belt 106, which belt may be driven by the continuously-moving belt-pulley 107, the said belt pulley receiving its motion through the medium of a worm-wheel 108 coaxial therewith, which engagesa worm or screw 109, formed upon one extremity of the aforesaid shaft 5. A bracket 110, arranged" at this point, constitutes a bearing or support for the aforesaid worm-wheel and pulley. The aforesaid crossed belt 106 passes about the pulley 111, which is rigid with the aforesaid reel 105, and the pulley and reel are both supported upon a suitable'bracket 112 in any suitable manner.

In operation it should be understood that the shaft 5 is continuously driven, and this shaft, by means of the cam 91,,aflords means for advancing the wire 29 periodically by reason of the feed-lever 85. Beyond the feedthat when the wire 29 is being advanced by the feed lever thedies 18 and 22 are maintained apart, so as to permit such an advance, and after the advance is completed these dies then cooperate to clamp the wire between them. They clamp the wire at their upper edges by means of the concave recesses 27 and 28 aforesaid, which recesses are, by the way, of littledepth, so that the upper portion of the work or wire when clamped protrudes laterally above the dies and above their upper faces. hen clamped in this manner, the pointing-die 32 is advanced, sliding upon the upper faces of the dies '18 and 22 in such a manner as to shear ofl a portion of that part of the wire which protrudes above the recesses 27 and 28, in this way forming the point of the nail. This die 32 is actuated by means of the bell-crank lever 64, which receives its motion from the cam-groove 51, formed in the cam 50. Vhile the wire 29 is clamped between the dies 18 and 22 and preferably while the point is being formed the dies 64 are advanced in such manner as to clamp the wire between them. These dies are advanced by reason of the cam 68, which operates through the rollers 69 to throw apart the lower extremities of the levers 61, which carry the said dies 64. After the dies 64: have clamped the wire in the manner described the levers 61 are then rocked in such a way as to move the dies 64: toward the outer faces of the dies 18, 22, and 32. In'this way the head of the nail is formed. Upon being released by the dies the wire is again advanced by the feed-lever 85, and the operation just described is repeated. In Fig. 5

' the dotted lines indicate how the clamping-dies operate to hold the wire while the point is being formed. It should be understood that the rocking movement of the lever 61, which movement forms the head, is possible on account of the form of the opening 70, the said opening being of enlarged diameter at the faces of the levers, as described. As the wire 29 is advanced the head of the nail which had just been formed is received in the aforesaid recesses 64, which recesses are formed for that purpose.

While I have shown in the accompanying drawings the preferred form of my invention, it will be understood that I do not limit myself to the precise form shown, for many of the details may be changed in form or po- It should be understood sition without affecting the operativencss or utility of my invention, and I therefore reserve the right to make all such modifications as are included within the scope of the following claims or of mechanical equivalents to the structures set forth.
